LHCb meets Theory: Probing the nature of the $X(3872)$ state using radiative decays
This is a traditional mini-worshop "LHCb meets Theory". Previous editions of this workshop were devoted to studies of charm abd beauty baryons,, double-heavy baryons, lineshape of the X(3872) state, double open charm tetraquark $T_{cc}^+$, prospects for the $T_{bc}$ and $T_{bb}$ tetraquarks and many other hot items, interesting both for the LHCb and Theory.
This edition is devoted to probing of the nature of the $X(3872)$ state using radiative decays. The nature of the $X(3872)$ state is a subject of hot discussinon and intensive studies for more than twenty years. Radiative decays, namely the ratio of the partial widths of the $X(3872)$ decays into the $\psi^{\prime}\gamma$ and $J/\psi\gamma$ final state potentially could shed light on the nature of the $X(3872)$ state, since the predicted ratio of radiative width is very sensitive to the assumed $X(3872)$ structure. The experimental situation (May 2024) is rather controversial, and there is no theory consensus. This worskhop provide the opportunity to discuss both theoretical and experiemtnal issues.
Recent LHCb results on the analysis of funr Run1 and Run2 datasets (2011-2018) have been reported at the CERN seminar, June 11, 2024 and appeared at arXiv at June 26, 24
